Embodiment 1

[0074] Such as image 3 (a) shows the schematic diagram of the connection relationship of the single-camera system. In order to illustrate the characteristics of this detection device, an obstacle wall 9 is set up in the system to highlight the characteristics of wireless transmission and reception of this device; The factory for processing steel wire heads, 5 is the thread rolling machine for threaded steel wire head processing, 7 is the rebar conveyor belt used for production, and 8 is the rebar for receiving and testing. Because of the super anti-interference ability of this device, although the processing There is a lot of noise in the factory, but this equipment can still detect the quality of threaded steel wire heads normally.

[0075] When working, the surface light source 6 is vertically irradiated on the threaded steel wire head 8, and at the same time, the industrial camera is placed in the vertical light direction to place the industrial camera 2 to transmit the im...

Embodiment 2

[0077] On the basis of Embodiment 1, if the system contains multiple cameras to detect the image information sent by multiple signal sources, such as image 3 As shown in (b), in the case of "multiple sending and one receiving", assuming that there are three image acquisition devices A, B, and C to collect image information at the same time, any image acquisition device can be used to work at the same time in practical applications.

[0078] Industrial camera C 1 、C 2 、C 3 Work in areas A, B, and C respectively, and transmit the image information collected at A, B, and C to the wireless receiver through the wireless transmitter. At the image receiving end, use the wireless receiver to receive the signal, and then process the signal through the anti-collision module, such as Figure 4 As shown, and then transfer the currently selected image information to the PC, and perform image processing on the PC.

[0079] Such as Figure 5-Figure 7 As shown, the actual size of the re...

Abstract

The invention belongs to the technical field of image processing and judgment, and particularly relates to a separated detection system and method for detecting the size of a deformed steel wire head.The system comprises an image collection module, a transmission module, and an image processing module. The image acquisition module comprises a plurality of groups of industrial cameras and a plurality of groups of light sources; a plurality of wireless transmitters are respectively arranged on the cameras and are used for transmitting images acquired by the cameras to wireless receivers; anti-collision modules are arranged in the wireless receivers, and the anti-collision modules sort the groups of images and input the groups of images into an image processing module according to the sequence for reading; and the image processing module obtains the size information of the deformed steel wire head and judges whether the deformed steel wire head is qualified or not. The computer vision technology and the wireless transmission technology are combined, and the system is small in size and simple to arrange, and can be flexibly applied to production places such as a construction site factory. One set of equipment supports simultaneous work of a plurality of image acquisition equipment. Compared with a traditional detection method, the method greatly improves the detection efficiency and precision.

Description

technical field [0001] The invention belongs to the technical field of image processing and determination, and in particular relates to a separate detection system and method for the size of threaded wire heads. Background technique [0002] Rebar is widely used in the construction of houses, bridges, roads and other civil engineering projects, ranging from public facilities such as highways, railways and bridges, to the foundations, beams, columns and walls of house construction. Rebar is an indispensable structural material , so the quality of rebar is of great significance to the quality of the project. [0003] The detection of rebar is mainly based on the measurement of the major diameter, minor diameter, pitch and other parameters of the threaded steel wire head. In actual production, most manufacturers use manual calipers to measure the wire diameter of the rebar wire head. The measurement accuracy of this method is It is not high, the efficiency is low, the labor in...
